Smart Irrigation System for Circular Farms

(Project TulipsAndPopcorn)

TulipsAndPopcorn is a device-web-server system that efficiently waters sections of a circular farm. This project was created at the Carleton Stay Late and Make Sessions (http://staylateandmake.ca) as a potential entry to the 'Makers Against Drought' Challenge (http://artik.devpost.com)

Components of System

• Web Server (Django)
  • The web server will collect data from each of the farm devices connected, correlate it with weather patterns, and send commands to water certain sections.
• TI Launchpad Farm Device (gcc-arm with the TI Driver Library)
  • The Launchpad will establish a conenction to the server and perform actions that are sent back. It has the following sensors and actuators:
    • LSM303D 3-Axis Accelerometer and Magenetometer
    • DC Drive Motors
    • Moisture Sensors
    • Water valve Servo

Contents of Repo

• Test Phone application (Deprecated)
• Test Particle Photon Code (For testing Compass Board)
• TI launchpad Code

Development

Developing on the Tiva Launchpad

• Install the cross compiler for ARM
  • sudo apt-get install gcc-arm-none-eabi
• Create a new folder called SLAMTools
  • mkdir SLAMTools
  • cd SLAMTools
• Install lm4flash tool needed to communicate with the Tiva
  • git clone https://github.com/utzig/lm4tools.git
  • cd lm4tools/lm4flash/
  • make
  • sudo cp lm4flash /usr/bin/
• Go back to the SLAMTools directory

  cd ..
  

• Install OpenOCD (the Open On-Chip Debugger) with ICDI (in-circuit debug interface) support to flash and debug the LaunchPad
  • git clone git://git.code.sf.net/p/openocd/code openocd.git
  • cd openocd.git
  • ./bootstrap
    • NOTE: If a "libtool is not found" error is encountered, install libtool
    • sudo apt-get install libtool
    • NOTE: If a "aclocal is not found" error is encountered, install automake
    • sudo apt-get install automake
• Configure the debugger
  • ./configure --prefix=/usr --enable-maintainer-mode --enable-stlink --enable-ti-icdi
  • make
  • sudo make install
  • Go create a new folder to put all your Launchpad Code in
  • Clone the tiva123 demo from https://github.com/CarletonSLAM/tivac123
  • git clone https://github.com/CarletonSLAM/tivac123.git
• Plug in your Tiva to your PC
  • cd tivac123/gcc
  • arm-none-eabi-gcc -v
  • make
  • make deploy
    • Note: If you get an "ACCESS" Error, try
    • sudo make deploy
